The overall quality of the ink is excellent, however it is a little un-nerving to see that 1/4 of my ink is still left in the cartridge unused, according to the ink level indicator on my printer, when I am forced to replace the cartridge because the quality gets poor. I wouldn't have complaints if there was very little ink left in the cartridge at the time that I replace it, but it appears that I am consistently throwing money in the trash each time I replace a cartridge.
